i'm mark williams for pickup trucks.com and we're here in the mountains of
Arizona with the 2015 GMC sierra heavy duty trucks at 2500 and 3500 now we've
seen all the things that are brand-new about this truck at the state fair of
texas several months ago and we have the video and the stories to prove it on the
site but now we want to give you our impressions of what it feels like to get
behind the wheel and take this out in the real world
most of our time was spent with the duramax diesel into the hood a great
motor very powerful and a lot of updates actually on the software side that make
it more comfortable to drive around town as well as making a very confident and
capable vehicle towing both up steep hills and down steep grades
after our drive we were really surprised about how quiet interior cabin is with
all the windows rolled up and after poking around and asking a few questions
we find out that they completely redesigned all three of the cab
configurations regular double and crew cab much quieter inside much more
insulation so you're not hearing any wind noise or engine noise and that just
creates a more comfortable and a quieter and more relaxing heaven when you're
driving
GMC knows that if you're interested in the sierra HD
you're probably interested in doing some towing that's why they've spent a lot of
time and redesigning strengthening making this almost a bulletproof pitch
that allows you to toe probably just about anything you can hook up behind it
but that's not the only thing that they've done they've also improved the
breaking calibrations and also the exhaust brake to be a little more
aggressive in a little more capable of holding that weight that's behind your
truck in control and that's exactly what we found we had a chance to talk about a
half a dozen different trailers some from about 6,000 pounds on up to about
15,000 pounds and we played with the exhaust breaks played with the cruise
control and found that this was a very confident and very comfortable and very
safe feeling vehicle with all the power the duramax is offering and all the
control that a lot of the sensors and electronics are provided
another detail we like about these new Sierra hd's the crew cab has been
reconfigured b-pillar has been pushed forward makes getting in and out for
rear passengers much easier and gives you more leg room as well as the extra
cutouts they give you in the roof for more Headroom another aspect of the 2015
GMC sierra HD is that we like our the new bed features that they are now
offering standard corner bed step and grab handle also an optional spray in
bedliner upper and lower tie downs and on the denali packages you get this
unique face plate on the back of the pickup it trim packages basically
carryover sierra SLE SLT and denali the new pricing structure expect a little
bit of a bump from the 2014 models
how do we feel about this truck we know that the chassis and the suspension is
essentially carry over but the improvements that they have made with
the materials that they use in the cabs and also the additional towing
capability that they have given this truck
we think makes this one of the top players in the segment
yeah
